I don't know. I'm an Oriental and referred to myself as such several times, and didn't know there's anything wrong with the usage.
Besides Oriental is not just Chinese people, it can be anybody from East Asia.

Well. Maybe People that live in America doesnt think the same? but I think it is really offensive.

It is like calling black people the N word. Even some black people think the word N are really offensive because of the history.

Like I said CHINESE PEOPLE ARE PEOPLE, NOT RUGS

The word oriental is nothing like saying the n word to a black person...
you are just trying to make something that is not racist seem racist.
By the way oriental doesn't just refer to Chinese people...

if i saw some Australian walk past and calling me an oriental i wouldnt like it much its just like calling An Australian Skippy or somthing like that its not rasist BUT it isnt someones name
just call me girl i you dont know my name

It's considered offensive by some not because there's such thing as an Oriental rug, but because during the 1800s the "Orient" was thought to be a place of luxury, fantasy and sexual escape by Westerners.

If you've ever read Kubla Khan by Coleridge this is an example.

People living in the Orient were basically dehumanized because 'luxury' was not a good thing--they were romanticized but in this process they lost their agency as rational, indiviual beings. Basically... Europeans contrasted their enlightened reason with 'Oriental' passions and lack of intellect.

i don't find it offensive. i just think it sounds kind of weird... where i live everyone calls asians, asians. no one says orientals. i remember one time one kid said oriental and i was like ...who still says that? but i find chink to be very offensive. i will kick your ass if you ever say that to me. chinaman is bad too but not as bad as chink.
